DA: A Core Blockchain Guarantee
- Data availability (DA) is a core guarantee of all blockchains, ensuring everyone can access and verify the state.
- Rollups highlight DA by separating it, but every blockchain needs it for agreement on shared state.

- "Good" DA is verifiable and has strong liveness, crucial for high-value transactions.

- Factors like network effects and data availability sampling differentiate DA layers.
